Description

Technical Field

[0001] The utility model relates to the technical field of bubble paper pressing, in particular to a humidifying device and a bubble paper pressing machine. Background Art

[0002] Bubble paper, with its unique concave-convex micro-bubble structure, achieves excellent shockproofing. This structure effectively absorbs and disperses impact forces during transportation, providing stable protection for items. Conventional bubble paper machines typically use a direct pressing method with bubble rollers to compress and shape the paper. Direct pressing provides high tensile strength, but leaves insufficient room for deformation during bubble formation, which can easily lead to bubble breakage. Furthermore, the bubbles produced by direct pressing lack sufficient toughness and stiffness. To address these issues, existing technologies employ a wetting device to apply atomized moisture to the surface of the base paper sheet before bubble formation to reduce its tensile strength. Heat and dry the surface during bubble formation to further stabilize the bubble paper. However, this wetting device, mounted above the base paper sheet and spraying water directly onto the moving sheet using a downward spray method, suffers from the following drawbacks: low water mist utilization: only a portion of the water mist sprayed onto the base paper sheet adheres to the sheet, while the remainder dissipates into the air; and the base paper sheet receives the water mist only on one side, resulting in low humidification efficiency and incomplete humidification. Utility Model Content

[0003] The utility model aims to solve the technical problems existing in the prior art and provides a humidifying device and a bubble paper pressing machine, which humidifies base paper sheets by setting a relatively closed humidifying chamber, thereby greatly improving the utilization rate of water mist and the humidification effect of the base paper sheets.

The ultrasonic atomizer atomizes the water from the water tank to form water mist, which is blown to the mist guide hood by the fan. The upper end opening of the mist guide hood constitutes the mist outlet.

[0014] The present invention further provides a bubble paper pressing machine, comprising a frame, a bubble pressing mechanism mounted on the frame, and a paper placing roller for placing a base paper roll; and further comprising a humidifying device as described above in the present invention, wherein the humidifying box is arranged on a sheet conveying path between the paper placing roller and the bubble pressing mechanism to humidify the sheet before bubble pressing.

[0015] Furthermore, the bubble pressing mechanism includes a pre-shaping assembly and a bubble pressing assembly sequentially distributed along the conveying direction of the sheet material.

A temperature sensor is also provided inside the foam pressing roller to detect the current temperature of the foam pressing roller. The output of the temperature sensor is connected to a circuit board, which is connected to the heating rod to control whether the heating rod is heated or not according to the temperature data transmitted by the temperature sensor.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The humidifying mechanism of the present invention includes a humidifying box, a first guide roller and a second guide roller, which can form a relatively closed humidifying chamber, so that the water mist entering the humidifying chamber is not easily dissipated to the outside, which can greatly improve the utilization rate of the water mist. In addition, the sheet enters the humidifying chamber to receive the water mist. Since the water mist gathers in the humidifying chamber, the upper and lower surfaces of the sheet can be exposed to the water mist, thereby greatly improving the humidification effect of the sheet, and further improving the bubble forming effect of the sheet.

[0019] 2. The present invention further provides a water coating roller in the humidifying chamber, which can be used to brush the surface of the sheet, thereby further improving the humidifying effect of the sheet.

[0020] 3. This utility model features an inlet and outlet on one side of the humidification box, allowing sheet materials to enter and exit the humidification chamber through the same inlet and outlet. This reduces the number of connections between the humidification chamber and the outside world, thereby reducing the possibility of water mist within the humidification chamber dissipating outward. In particular, the water coating roller is positioned near the inlet and outlet, which can be used to block the inlet and outlet to a certain extent, further reducing the possibility of water mist within the humidification chamber dissipating outward through the inlet and outlet.

[0021] 4. The humidification box includes the box body and cover plate, making paper feeding more convenient. In particular, a sealing strip is installed at the other end of the cover plate. This sealing strip presses against the sheet material to prevent water mist from escaping from the gap between the cover plate and the sheet material. In addition, the sealing strip can be used to evenly brush away water droplets attached to the surface of the sheet material. In particular, the sealing strip is a sponge or foam that can absorb moisture, which facilitates brushing the absorbed moisture onto the sheet material.

[0022] 5. The humidification baseplate and its mist holes enable targeted, concentrated spraying of the sheet material, further enhancing the sheet material humidification effect. In particular, the humidification baseplate is tilted, with a reflux gap formed between its lower end and the inner side of the humidification chamber. This prevents condensed water from accumulating on the baseplate and affecting the mist discharge effect of the mist holes, and facilitates the reflux of accumulated water.

[0023] 6. The setting of the mist guide hood can greatly improve the mist guide efficiency.

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments; however, the humidifying device and bubble paper pressing machine of the present invention are not limited to the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0041] In addition, unless otherwise specified, in the description of this utility model, "plurality" refers to two or more; "at least one group" refers to one or more groups. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can mean: A exists alone, A and B exists simultaneously, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0042] See Figure 1-Figure 7As shown, a humidifying device of the present invention includes an atomizing mechanism 20 and a humidifying mechanism 10. The atomizing mechanism 20 is used to generate water mist and is provided with a mist outlet 81. The humidifying mechanism 10 includes a humidifying box 1, a first guide roller 2 and a second guide roller 3. The interior of the humidifying box 1 forms a humidifying chamber, and the mist outlet 81 of the atomizing mechanism 20 is connected to the humidifying chamber. The first guide roller 2 is arranged in the humidifying chamber, and the sheet to be humidified is introduced into the humidifying chamber through the first guide roller 2 so that water mist adheres to its surface. The second guide roller is arranged outside the humidifying box 1 and is parallel to the first guide roller 2 to guide the humidified sheet out of the humidifying chamber. Specifically, an inlet and outlet 13 connected to the humidifying chamber is provided on the top of one side of the humidifying box 1, so that the sheet enters and exits the humidifying chamber through the same inlet and outlet 13, which can reduce the connection between the humidifying chamber and the outside world, thereby reducing the possibility of the water mist in the humidifying chamber dissipating outward. The sheet material requiring humidification is specifically a base paper sheet material that can be formed into bubble paper through bubble pressing treatment, or a paper sheet material, but is not limited thereto. Other non-paper sheets requiring humidification treatment may also be used.

[0043] As a preferred embodiment, the humidification mechanism 10 further includes a water coating roller 4, which is positioned within the humidification chamber and parallel to the first guide roller 2. As the sheet passes over the water coating roller 4, the water mist absorbed by the water coating roller 4 is applied to the sheet surface and / or water droplets adhering to the sheet surface are applied to the water coating roller 4. Specifically, in this embodiment, the water coating roller 4 is positioned near the inlet and outlet 13. This allows the water coating roller 4 to block the inlet and outlet 13 to a certain extent, further reducing the possibility of water mist within the humidification chamber dissipating outward from the inlet and outlet 13. The first guide roller 2 is located on the side of the water coating roller 4 away from the inlet and outlet 13. The second guide roller 3 is located outside the inlet and outlet 13 and is equipped with two positioning rings 31. The two positioning rings 31 define a paper feed area on the second guide roller 3, preventing the sheet from shifting on the second guide roller 3. The ends of the second guide roller 3 are connected to fixed plates 17, respectively, located at the longitudinal ends of the humidification chamber 1.

[0044] The sheet material entering the humidification chamber through the inlet and outlet 13 passes sequentially through the water coating roller 4, the first guide roller 2, the inlet and outlet 13, and the second guide roller 3. The sheet material then passes upward around the water coating roller 4 and downward around the first guide roller 2 before passing from above the first guide roller to the second guide roller 3. This allows moisture absorbed by the water coating roller 4 to be applied to the sheet material surface, enhancing the humidification effect. Furthermore, the water coating roller 4 is fitted with a water absorption cylinder 41, which is made of sponge or foam, to significantly enhance its water absorption performance. In other embodiments, the sheet material entering the humidification chamber through the inlet and outlet passes sequentially through the first guide roller, the water coating roller, the inlet and outlet, and the second guide roller. This allows the water coating roller to not only apply moisture absorbed by the roller to the base paper sheet but also evenly apply any water droplets adhering to the sheet surface.

[0045] The above-mentioned humidifying box 1 includes a box body 11 and a cover plate 12, and the cover plate 12 is set on the cover plate 12 in an openable and closable manner to facilitate the paper threading operation during the first operation. Specifically, one end of the cover plate 12 is rotatably connected to the box body 11, so that the cover plate 12 can be flipped up and down to close or open. In the closed state, the gap between the other end of the cover plate 12 and the box body 11 forms an inlet and outlet 13 to allow the sheet to enter and exit the humidifying chamber. In addition, a sealing strip 121 is installed at the other end of the cover plate 12. The sealing strip 121 is pressed on the sheet that is about to leave the humidifying chamber, and the sealing strip 121 is sponge or foam, preferably foam, to improve the wear resistance of the sealing strip 121. In this way, on the one hand, the sealing strip 121 can be used to reduce the gap between the cover plate 12 and the sheet to prevent water mist from escaping from the gap. On the other hand, the sealing strip 121 can be used to brush the sheet, so that the moisture adsorbed by the sealing strip 121 is brushed on the sheet, and the water droplets attached to the sheet can also be brushed evenly.

[0046] A positioning member is provided on the inner side of the box body 11 at a position corresponding to the other end of the cover 12, for positioning the other end of the cover 12 when the cover 12 is in the closed state. As a preferred embodiment, the positioning member is a spring ball 14, which can realize barrier-free opening and closing and effective positioning of the cover 12 through the automatic extension and retraction function of the spring ball 14.

[0047] As a preferred embodiment, a humidifying base plate 15 is provided in the humidifying chamber, and the sheet material entering the humidifying chamber is located above the humidifying base plate 15. The humidifying base plate 15 is provided with at least one group of mist holes 151, and each group of mist holes 151 includes a plurality of mist holes 151 spaced apart along the width direction of the sheet material. The arrangement of the humidifying base plate 15 and the mist holes 151 thereon can carry out targeted concentrated spraying on the sheet material, so that the water mist is sprayed on the sheet material as effectively as possible, thereby further improving the humidification effect of the sheet material. The humidifying base plate 15 is arranged at an angle, and a reflux gap 152 is formed between its lower end and the inner side surface of the humidifying chamber. In this way, it is possible to prevent the accumulated water generated by the condensation of the water mist from gathering on the humidifying base plate 15 and affecting the mist discharge effect of the mist holes 151, and is conducive to the reflux of the accumulated water. A mist inlet 16 is provided at the bottom of the humidifying chamber, and the mist inlet 16 is connected to the mist outlet 81 through the pipe 30.

[0048] In this embodiment, the atomizing mechanism 20 includes a water tank 5, an ultrasonic atomizer 6, a fan 7 and a mist guide hood 8. The fan 7 is arranged in the ultrasonic atomizer 6, the ultrasonic atomizer 6 is arranged below the water tank 5, and the mist guide hood 8 is arranged in the water tank 5. The mist guide hood 8 is funnel-shaped and narrow at the top and wide at the bottom. The area inside the water tank 5 located outside the mist guide hood 8 forms a water storage area. The ultrasonic atomizer 6 atomizes the water from the water tank 5 to form water mist. The water mist is blown by the fan 7 to the mist guide hood 8. The upper end opening of the mist guide hood 8 constitutes the mist outlet 81 of the atomizing mechanism 20. Figure 7As shown, a plurality of atomizing ports 61 and air outlets 62 are provided on the top of the ultrasonic atomizer 6. The water mist generated by the atomizing port 61 enters the mist guide hood 8 and flows upward under the action of the air flow blown out by the air outlet 62, and is finally blown out from the mist outlet 81 of the mist guide hood 8.

[0049] The working principle of the humidifying device of the present invention is as follows:

[0050] Paper feeding: Open the cover 12, and pass one end of the sheet upward around the water coating roller 4, then downward around the first guide roller 2, then out from above the first guide roller 2, and downward around the second guide roller 3. The paper feeding direction of the sheet is as follows: Figure 14 After the paper is threaded, cover the cover 12.

[0051] Humidification: Activate the ultrasonic atomizer 6, causing the atomizing mechanism 20 to continuously output water mist. This mist flows along the pipe 30 into the lower space of the humidification chamber of the humidification box 1 (i.e., the space below the humidification base plate 15). The mist is then blown upward from the mist holes 151 of the humidification base plate 15, directly onto the sheet below the first guide roller 2. The mist rapidly absorbs the mist onto the surface of the original sheet. Simultaneously, the mist fills the upper space of the humidification chamber, causing the water coating roller 4 and the sealing strip 121 on the cover plate 12 to absorb moisture. As the sheet moves, the water-absorbed water coating roller 4 and sealing strip 121 apply water to the moving sheet, evenly distributing the absorbed water droplets. Ultimately, the sheet surface is evenly humidified. The humidified paper fibers absorb water and expand, significantly reducing the sheet's tensile strength and making it easier to form during the subsequent foaming process. As water mist continuously enters the humidification chamber, it will condense and produce accumulated water after accumulating to a certain amount in the humidification chamber. The accumulated water flows to the mist inlet 16 at the bottom layer through the aforementioned reflux gap 152 and flows back to the water storage tank 5 through the pipe 30.

[0052] Therefore, the humidification device of the present invention, by providing the humidification box 1, the first guide roller 2, and the second guide roller 3, can form a relatively closed humidification chamber, so that the water mist entering the humidification chamber is not easily diffused to the outside, which can greatly improve the utilization rate of the water mist. In addition, the sheet enters the humidification chamber to receive the water mist. Since the water mist gathers in the humidification chamber, the upper and lower surfaces of the sheet can be exposed to the water mist, thereby greatly improving the humidification effect of the sheet, and further improving the bubble forming effect of the sheet. In particular, the present invention further provides a water coating roller 4 and a sealing strip 121, which can brush the surface of the sheet, thereby further improving the humidification effect of the sheet.

[0053] See Figures 1-14As shown, a bubble paper pressing machine of the present invention includes a frame 40, a bubble pressing mechanism 60 installed on the frame 40, a paper placing roller 50 for placing a base paper roll 90, and a humidifying device described in the above-mentioned present invention. The above-mentioned sheet is a base paper sheet 100 from the base paper roll 90, and the humidifying box 1 is arranged on the base paper sheet conveying path between the paper placing roller 50 and the bubble pressing mechanism 60 to humidify the base paper sheet 100 before bubble pressing.

[0054] Furthermore, the bubble pressing mechanism 60 includes a pre-shaping assembly and a bubble pressing assembly, arranged sequentially along the conveying direction of the base paper sheet 100. The pre-shaping assembly includes two shaping rollers 601, positioned vertically and oppositely, for pre-shaping the moistened base paper sheet 100 into a wavy shape. The bubble pressing assembly includes two bubble pressing rollers 602, positioned vertically and oppositely, for pressing the pre-shaped base paper sheet 100 into bubble paper. The upper bubble pressing roller 602 is floating and rotatable toward each other, pulling the base paper sheet 100 during the bubble pressing process and providing force for the paper sheet 100 to travel. Similarly, the upper shaping roller 601 is floating and rotatable toward each other. Each shaping roller 601 is provided with a plurality of annular grooves spaced along its axial direction, creating a wave-like pattern on its surface that extends along its axial direction. There are many convex particles and concave parts distributed on the surfaces of the two bubble pressing rollers 602, and the convex particles and concave parts are hemispherical respectively. When the two bubble pressing rollers 602 are performing the pressing operation, the convex particles and concave parts on one bubble pressing roller 602 are engaged with the concave parts and convex particles on the other bubble pressing roller 602 respectively.

[0055] The present invention further comprises a cutter component 70 , which is mounted on the frame 40 and located on the side of the bubble pressing component facing away from the pre-shaping component, for cutting the bubble pressing paper into a suitable length; the cutter component 70 is a circular blade.

[0056] In this embodiment, the foam roller 602 is hollow and contains a heater rod 603. When heated, the heater rod 603 transfers heat to the foam roller 602, raising its temperature. A temperature sensor 604 is also located within the foam roller 602 to detect the current temperature of the foam roller 602. The output of the temperature sensor 604 is connected to a circuit board (not shown), which is connected to the heater rod 603 and controls whether the heater rod 603 is heated based on the temperature data transmitted by the temperature sensor 604. The circuit board uses a slip ring as an electrical bridge to supply power to the heater rod 603. When the heater rod 603 heats up, it transfers heat to the foam roller 602 via thermal radiation, raising its temperature. The temperature sensor 604 detects the current temperature of the foam roller 602 and transmits the data to the circuit board via the slip ring. When the temperature of the foam roller 602 reaches a preset temperature, the electronic control board controls the heater rod 603 to stop heating.

[0057] In this embodiment, the bubble compression mechanism 60 is located at the top of the frame 40, the atomization mechanism 20 is located at the left or right side of the bottom of the frame 40, the humidification mechanism 10 is located approximately in the middle of the frame 40, and the paper placement roller 50 is located at the lower-middle position on the rear side of the frame 40. A paper guide 80 is also provided at the top rear side of the frame 40 to guide the base paper sheet from the humidification mechanism 10 toward the bubble compression mechanism 60. The paper guide 80 is equipped with multiple third guide rollers 801 arranged in parallel. Specifically, there are three third guide rollers 801, which are arranged in a roughly triangular pattern. The first guide roller 2, the second guide roller 3, and the third guide roller 801 are also referred to as paper guide rollers.

[0058] The present invention provides a bubble paper pressing machine, which operates as follows: a base paper sheet 100 from a base paper roll 90 enters a humidifying chamber 1. The humidified base paper sheet 100 exits along a second guide roller 3 and, guided by three third guide rollers 801 of a paper guide frame 80, passes through two shaping rollers 601. After being shaped into a wave shape by the shaping rollers 601, the sheet passes through two bubble pressing rollers 602. The bubble pressing rollers 602 press the waved base paper sheet 100 into bubble paper through a pressing operation. The paper is then heated and dried to dehydrate the fibers within the paper, allowing the paper to retain the shape formed by the pressing rollers. This results in a more resilient and stiffer bubble paper. The pressed and dried bubble paper is then cut to the desired length by a cutter assembly 70.

[0059] Regarding the structure and working principle of the humidifier, please refer to the previous description thereof, which will not be repeated here.

[0060] The humidifying device and bubble paper pressing machine of the present invention do not involve parts (such as other structures and working principles of the bubble pressing mechanism 60, and the specific structure and working principle of the cutter component 70) that are the same as those in the prior art or can be implemented using the prior art.

[0061] The above embodiments are only used to further illustrate a humidifying device and a bubble paper press of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the scope of protection of the technical solution of the present invention.
